Good morning evryone and thank you for your attention/help. I've a Panasonic KX-TEB308 to drive 4 internal phones, no external lines, very simple configuration. I would like that the first connector will be assigned to dialling number "1", the second to "2".. and the forth to "4". The phones have to call each other with one key, it seems impossible cause the Panasonic Maintenance Console software has only 3 preconfigured plans and doesn't allow to add a new one, how could I overcome this? I would know what other settings I've to add to a "vergin/just resetted" PBX ho have the 4 lines working in this way. Thank you really a lot for your help!
